This invention relates toa magazine elevatmg and lowering mechanism andpart cularly to a device for rais ng and lower ng the magazine of acharging machine for gas generators with respect to thegenerator,together with the mechanism for holding themagazine in gastight engagement with said. gen erator. 1 j p a 7 In one type ofcharging machine as heretotore constructed, in order to permit theremovahof the truck and magazine carried thereby from the generator,both the truck and magazine have been moved relatively to one another,the truck being elevated above its normal support so that it remainsunsupported and the magazine being simultaneously moved downwardly intooperative position on the generator. In this construc tion, the entireweight of the truck, magazine and the structure connected thereto issup-,

ported by the upper flange of the generator;

7 Further, to provide a gas tight engagement between the magazine andthe generator it has usually been necessary to bolt thesetwo memberstogether. This, of course involves considerahletime, is a tediousoperation and consequently increases the cost of the manipulation andoperation of thecharging de vice; r I 7 An'object ofmy inventionis tosimplify charging machines as'heretoforeconstructed and provide amagazine construction readily movable into and out of operativeposition,that is simple in construction and eat cient in operation. r V

The invention accordingly comprises a 7 magazine carried on a truckmounted to run on rails thatjis movable to and from operative positionin combinationwith meansto lower said magazine into engagement-with;

' the generator while maintaining the truck in its normal position onsaid rails. c o

ings in which Fig. 1 is a fragmentary end elevation partly in section ofa charging device inoperative position, showing the truck and themagazine in charging position and illustrating an embodiment of theinvention; Fig. 2 is a fragmentary side elevation of Fig. l partlybroken away andFig. 3 is a detail elevation partly in "section .of thecradle shown in Fig. 2.

Inthe preferred embodiment of the invention illustrated on the drawing,1 indicates the generator of the usual gas producing ma. chine, having aflange 2 supporting the casting 3. I This casting has a plurality oflugs integral with or fastened thereto in any suitablemanner. v I

Traclgs-55 are disposed ateacli side of the generator, and runningthereon are the wheels 6 of the truck, comprisingthe channel bars. 8, 8.Fastened preferably to each of the side channel bars bybolts .9mothersuitable, means are snpports or cradles 10, which extend away fromtlfe channel bars as indicated at 11, and are provided, at the.

ends 12 with circular or 'U-shaped bearing portions 13. Eachcradle' 10has bolted thereon as at ll a detaining spring 15 the function of whichwill be hereinafter explained.

- A magazine 16 is mounted on the truck adapted to move therewith. It isunderstood that in normal operation the magazine oithe charging deviceis. in gas tight engagement with thegenerator and remainsthuspositioneduntil it is desired to gain access to the generator orinspect the charging device, whereupon the magazine is disengaged fromthe generator and moved onthe truck into position,-'where inspection ofthe charging device orgen erator may be had. In order to permit thereadyremoval of the charging device and to maintai it in gas tight engagment-with the, generator when in operative position, an elevating,lowering and clamping structure i'spreferably provided at each side ofthemagazine. It is understood, ofcourse,

I iu u, mar-sinus- 3.1 ftthat any desired number of these clamping andmoving devices may be used in conjunctionwith the magazine and truck.

In Fig. l shafts or rods 18 are shown fixed in bearings 19 integral withor fastened to each side of the magazine at 20. Bifurcated levers 21 arepivoted on these shafts 18 and their movement toward the magazine islimited by lugs 22 extending from the magazine. Mounted in the arms oflevers 21 are the rods 23, these rods being so positioned that when thelevers are swung about their pivots away from the magazine, they engageand rest in the circular or U-shaped bearing portions 13 of cradles 10.Pivoted on rods 23 are hooks or clamps 24 which have positioned thereonor integral therewith handles 25. A stop 31 is formed on the casting 3and is adapted to contact with the hook 24 when in lowered position toproperly register the magazine with respect to the generator o ening.This can readily be accomdih'ed y moving the magazine with'the ooks 24in lowered position into contact wi hthis stop.

l e upper extremities of levers 21 are secured to s eeves 26frictionally engaging nut or circular niembers 26' which are in threaded engagement with the threaded rods 27 pivoted to lugs 28 extendingfrom the magazine. Hand wheels 29 integral with or secured to the notmembers are provided to readily manipulate levers 21. The nut members 26have projections at the end peripheral edge adjacent the lugs 28, whichpro ections engage the ends of sleeves 26. W en the nut members arerotated by the hand wheels 29 theyturn in the sleeves 26 which do notrotate with the nut members but move lorigitudinally of the rods 27 noperation; assuming that the magazine has been moved over the generatoras shown in dotted lines Fig. 1, and it is desired to lower it into gastight engagement with said generator, hand wheels 29 are turned,gradually swinging the threaded rods 27 upwardfrom the dotted to thefull line positions,

Fig. i 1) and simultaneously rocking the bifurcated levers 21 aboutshaft 18 until the leversengage lugs 22, whereupon continued movement ofthe levers causes a downward pressure to be exerted on the magazine,forcin it into engagement with the generator-n ooks 24, having beenreleased from the detention spring 15 and moved into position beneaththe lugs, are lifted upwardly by the movement of levers 21 until theyengage the lugs 4, continued movement of the levers forcing the-magazinedown and causing an upward pressure to be exerted on the lugs 4 bythebooks 24 so that there results a'gas tight engagement between themagazine and generator. It will be noted that throughout this-operationthe truck remains on the tracks and that only the dead weight of themagazine rests on the generator, there being clearances 30 between theU-shaped bearing supports of the cradle and the rods 23 when themagazine and generator are in engagement.

To elevate the magazine, it is only necessary to turn the hand wheels inthe opposite direction, whereupon the threaded rods are gradually movedto the dotted line positions,

ig. 1, and the bifurcated levers are rocl-red aboutshafts 18 until theclearances30between rods 23 and U-shaped bearing portions 13 are takenup. This movement is sufficient to move the book 24 away from lugs 4,whereupon the hooks 24 are readily swung about rods 23 to move handles25 into detaining springs 15 thus clearing stop 31 and permittingmovement of the truck in either direction towards or away from stop 31.This can be accomplished by simply kicking the handle up into engagementwith spring 15. Continued movement of levers 21 causes the U-shapedbearings and rods 23 to act as a fulcrum about which lever 21 is moved,elevating the magazine and supporting it on the truck in the U-shapedbearings '13. The charging device may then be readily moved intoinspection position away from the generator.

It will be noted that the mechanism'hereinbefore described is simple inconstruction, eflicient in operation, provides a ready means forelevating and lowering the magazine while maintaining the truck inposition on its supporting surface, and also provides a gas tight clampbetween the magazine and generator that is readily applied and removed.

It will, of course, be understood that while a specific embodiment ofthe invention has been shown and described. various changes in thedetails thereof may be made by those skilled in the art, and theinvention is not to be limited to the structure disclosed but 011% bythe scope of the appended claims.
